視神経乳頭ドルーゼンの2例

Two cases of optic disk drusen

　両眼性の視神経乳頭ドルーゼンの2例について報告した．1例は片眼に視野異常を伴い，乳頭面上に突出の著明な34歳男子である．他の1例は62歳男子で初診時に乳頭浮腫を示し，6年後に視神経乳頭ドルーゼンが確認され，明らかな視野狭窄の進行を示した．視神経乳頭ドルーゼンにおいて蛍光眼底造影検査でもうっ血乳頭様所見を示すことがあり，その診断には頭蓋内病変の検査を含めた総合的検査が必要である．

We observed bilateral drusen of the optic nerve head in two cases. The first case, a 34-year-old male, present-ed with unilateral visual field loss. The fluorescein angiogram showed characteristic autofluorescence of the disc drusen. The second case, a 62-year-old male, was initially diagnosed as bilateral papilledema on account of gradually failing vision, unilateral visual field loss and typical fundus findings. No intracranial lesions were detected by thorough neurological exami-nations. Six years later, funduscopy revealed prominent drusen located on the atrophic disk bilaterally. The visual fiel loss had progressed further during the inter-vening period.
